3.5.4 Immunity Requirements

The immunity requirements for frequency converters depend on the environment where they are installed. The
requirements for the industrial environment are higher than the requirements for the home and office environment. All
Danfoss frequency converters comply with the requirements for both the industrial and the home/office environment.
To document immunity against electrical interference, the following immunity tests have been performed on a frequency
converter (with options if relevant), a screened control cable and a control box with potentiometer, motor cable, and motor.
The tests were performed in accordance with the following basic standards. For more details, see Table 3.17
•
EN 61000-4-2 (IEC 61000-4-2): Electrostatic discharges (ESD): Simulation of electrostatic discharges from human
beings.
•
EN 61000-4-3 (IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude modulated simulation of the
effects of radar and radio communication equipment, as well as mobile communications equipment.
•
EN 61000-4-4 (IEC 61000-4-4): Burst transients: Simulation of interference brought about by switching a contactor,
relay, or similar devices.
•
EN 61000-4-5 (IEC 61000-4-5): Surge transients: Simulation of transients brought about by lightning strikes near
installations.
•
EN 61000-4-6 (IEC 61000-4-6): RF Common mode: Simulation of the effect from radio-transmission equipment
joined by connection cables.
